COMBINED AlR-EXHAUSTER AND WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 330,366, dated November 17, 1885.

Application filed March 31, 1885.

To all whom it may concern:

Be it known that I, THOMAS ARTHUR, of Bangor, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in a Combined Air-Exhauster and Water-Elevator, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, ,forming part of this specification, and which is a sectional side elevation of my improvement.

The object of this invention is to provide a simple and reliable mechanism for elevating water or drawing air from mines and other places.

The invention relates to a combined airexhauster and water-elevator constructed with a conical tube inserted in a water-pipe and connected by an air-pipe with the upper part of the short arm of an elevator, the lower end of the said short arm being provided with a water-seal, and the upper end of the long arm of the elevator being extended downward past the end of the air-pipe, and its lower part being provided with an air-inlet, whereby water and air can be readily withdrawn from mines and other places, as will be hereinafter described and claimed.

A is a pipe open atboth ends, and connected at its upper end with a water-supply by a spout or other suitable' means. WVithin the upper end of the pipe A, and not in contact with it, is suspended a conical tube, B, with its smaller end downward. The larger upper end of the conical tube B is connected with one end of an air-pipe, O. The other end of the airpipe O is connected with the top part of the pipe D.

E is an invertedL-shaped tube, the upper end of which is secured air and water tight in the upper end of the pipe D, and is extended a little below the end of the air-pipe G. The lower end of the tube E extends down to the place from which the water or air is to be withdrawn.

In one side of the lower part of the pipe D E is secured a small air-inlet tubeornipple, F. WVith the lower end of the pipe D is con- Serial No. 160,787. (No model.)

nected a short elbow-pipe, G, to form a water-seal for the said lower end, to prevent air from entering the said pipe D from its lower end.

The construction at the lower end of the pipe D is immaterial so long as air is prevented from entering the said end and water allowed to flow out freely.

With this construction, as the water flows .into the pipe A past the conical tube B its tendency to form a vacuum in front of the said tube B draws the air from the said tube B and'from the pipe 0 and the pipe and tube D E connected with it. When the lower end of the pipe D is closed so as not to admit air, or when the said pipe contains so much water that its weight equals the suction-power of the exhauster A B, and the lower end of the tube E is immersed in water with the nipple F above the surface of the said water,water and air will flow through the said tube E into the pipe D, where they will separate, the water flowing out through the said pipe D and the air flowing through the pipe 0 and the conical tube B into the pipe A, so that as long as the said pipe A is supplied with water and the end of the tube E is immersed in water there will be a continuous outflow of water at the siphon G at the lower end of the pipe D. In case there be no water at the lower end of the tube E, air will be drawn up through the said tube E so long as the pipe Ais kept supplied with water.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A combined air-exhauster and waterelevator constructed substantially as herein shown and described, and consisting of the conical tube B, inserted in the water-pipe A and connected by the air-pipe O with the upper part of the pipe D, the lower end of the said pipe being provided with a water-seal, and the upper end of the tube E being extended downward past the air-pipe O, and its lower part being provided with an air-inlet, F, as set forth.

2. In a combined air-exhauster and waterelevator, the combination,with the upper part of the pipe D, having its lower end provided ter and air can be readily withdrawn from with a water-seal,and having the upper end of mines and other places, as set forth.

the tube E extended into the upper part of the said pipe, and provided near its lower end 5 with an air-inlet, F, of the pipe 0, the conival Witnesses:

tube B, and the water-pipe A, substantially CHESTER M. BUTZ,

as herein shown and described, whereby wa- JOEL SEARFOSE.
